ROTARY CUTTER.

SPECIFICATION forming part of Letters Patent No. 653,026, dated July 3, 1900.

Application filed September 2, 1899. Serial No. 729,309. (No model.)

T all whom t may concern;

Be it known that I, CHARLES S. LOCKE, a citizen ofthe United States, residing at Joliet, in the county of Will and State of Illinois,

have invented certain new and useful Improvements in Cutting-Machines, of which the following is a specification.

The object of this invention is the production of a cutting-mill for green bones, vegero tables, or othersubstances, the parts of which machine are easily accessible for cleaning and repair and which is simple and strong in its construction. A

In the accompanying drawings, Figure lis a side elevation of the cutting-machine. Fig. 2 is a plan view of the same, and Fig. 3 is a face view of the cutter-head.

Like letters of reference indicate corresponding parts throughout the several views.

A is the bed of the machine.

B is the drive-shaft, with the drive-wheel B rigidly secured thereon. B2 is a pinion, also fixed on the shaft B.'

C is the cutter-shaft, hav-ing a gear-wheel 2 5 C meshing with the pinion B2.

C2 is the cutter-head, rigidly1 fixed at the forward end of the cutter-shaft, having the cutting-knives C3 on its face.

D is the receptacle for containing the sub- 3o stance to be cut. This receptacle somewhat resembles in outline the quarter-section of a bowl. One of its sides is closed by the cutterhead C2, and the other by the follower D', pivoted upon its bearing-stud D2. The inner sur- 3 5 face of the receptacle D and the innerface of the followerD are corrugated to more securely hold the substance within said receptacle.

D3 is a bearing-Stud formed integral with the follower D and projecting therefrom, and

4o upon this stud the pinion D4 and its handwheel D5 are rotatably mounted. The pinion D4 meshes with the circular rack D6, secured to the curved outer wall of the receptacle D near to the upper edgothereof. This rack D6 is concentric with the stud D2 and is intended to be engaged by the pinion D4. The pinion D4 and the hand-wheel D5 are integral andr rotate together. The rotation of the handwheel D5 moves the follower D upon its piv- 5o otal stud D2.

As will be seen, the follower D', having its pivot-al axis extending vertically, is mounted to have a movement concentric with the curved circumference of the upper edge of the receptacle, which movement enables the operator to introduce new material without removing'the follower from the receptacle and in addition allows the contents to be visibly inspected at all times prior to passing into contact with the cutters.

In operation bones, vegetables, or other substances to be cut are placed within the receptacle D, the drive-wheel B rotated by hand or by power, and the hand-wheel D5 turned until the follower D forces the substance within the receptacle D into contact with the knives C2 of the cutter-head C2. The rotation of the drive-wheel B rotates the cutter-head C2, and the revolving knives C3 thereon slice off portions of the substance within the receptacle D as said substance is forced forward by the pressure of the follower DA applied by means of the hand-wheel D5. The downward movement of the cuttingknives C3 crowds the substance within the receptacle D toward the bottom of said recept-acle, and the tapering conformation of its interior, together with the corrugations on its inner surface, tend to crowd said contents toward the cutting-knives, making a partial self-feed of the substance to be cnt toward the cutting-knives. .When the receptacle D is emptied, the rotation of the hand-wheel D5 is reversed in direction and theffollower D fed backward to the end of the rack D5. A new supply of the substance to be sliced may then be placed in the receptacle D and the operation repeated.

To clean the machine, the follower D may be'turned 'upon its pivot to entirely open the side of the receptacle D which it is intended to close, or it may be moved to the opposite extreme for convenience inremoving 'the knives C5 from the cutter-head C2.

I claim as my inventionl. In a cutting-machine, in combination, a receptacle having an open upper end and two open sides, the walls of which receptacle are curved, and taper toward the bottom;v a rotatable cutter-head adapted to close one of said open sides of the receptacle; cuttingknives for said cutter-head; said receptacle IOO being located to one side of the rotatable center of said cutter-head; a follower in the receptacle, which follower is pivotally mounted to have a movement concentric With the curved circumference of the upper edge of the receptacle; and means for moving the follower to feed the substance to be cut into contact with the cutting-knives.

2. In a cutting-machine, in combination, a receptacle shaped substantially like a quarter-section of a bowl; a rotatable cutter-head adapted to close one of the open sides of the receptacle; cutting-knives for said cutterhead; a follower in the receptacle, which follower is pivotally mounted to have a movement concentric with the curved circumference of the upper edge of the receptacle; and means for moving the follower to feed the substance to be cut into contact with the cutting-knives.

3. In a cutting-machine, in combination, a receptacle shaped substantially like a quarter-section of a bowl; a rotatable cutter-head adapted to close one of the open sides of the receptacle; cutting-knives for said cutterhead; said receptacle being located to one side of the rota-table center of said cutter-head; a follower in the receptacle, which follower is pivotally mounted to have a movement concentric with the curved circumference of the upper edge of the receptacle; and a rack and pinion for moving the follower to feed the substance to be cut into contact with the cutting-knives.

4. In a cutting-machine, in combination, a receptacle having an open upper end and two open sides, also having a curved side wall tapering toward the bottom of said receptacle; a rotatable cutter-head adapted to close 011e of the open sides of the receptacle; said receptacle being located to one side of the rotatable center of said cutter-head; cutting-knives for said cutter-head; a verticallypivoted follower in the receptacle, which follower is pivotally mounted to have'a movement concentric with the curved circumference of the upper edge of the receptacle; a curved rack secured to the upper edge of said receptacle; a pinion pivotally mounted on said follower, for engaging said curved rack;

land a hand-wheel rigidly connected to said pinion for moving the follower to feed the substance to be cutinto contact with the cuttingknives.

5. In a cutting-machine, in combination, a cutter-head; a cutting-knife fixed thereon; an open receptacle; a pivoted follower in said receptacle; a stud on said follower; a pinion rotatably mounted on said stud; a curved rack fixed concentric with relation to the axis upon which the follower moves; and a hand-wheel forrotating said pinion.

6. ln a cutting-machine, in combination, a cutter-head; a cutting-knife fixed thereon; an open receptacle; a pivoted follower for closing one side of said receptacle; a stud on said follower; a curved rack concentric with the pivotal bearing of the follower; a pinion rotatably mounted on said stud, adapted to engage said rack; and a hand-wheel for rotating said pinion.

7. In a cutting-machine, in combination, a main shaft; a drive-wheel on said shaft; a cutter-shaft; a cutter-head on the cuttershaft; a cutting-knife on the cutter-head; au open receptacle, one of the sides of which is closed by the cutter-head; a pivoted follower for closing one side of said receptacle; a stud on said follower; a curved rack concentric with the pivotal bearing of the follower; a pinion rotatably mounted on said stud, adapted to engage said rack; and a hand-wheel for rotating said pinion.
